Description

Technical Field

[0001] This invention relates to the field of memristor self-learning circuit design, and particularly to a memristor decision circuit that integrates emotional habituation and behavioral reinforcement. Background Technology

[0002] With the deep integration of artificial intelligence, big data, and the Internet of Things, the amount of data that people need to process is growing exponentially, placing unprecedented demands on the computing power and energy efficiency of computing systems. However, traditional computing systems are based on the von Neumann architecture, which separates computing units from storage units. Data needs to be frequently moved between the two, and this inherent design has led to many bottlenecks such as the "memory wall" and the "power wall."

[0003] The biological brain does not separate computation and storage when processing information; instead, it achieves in-memory computation in a highly parallel manner. This provides a natural model for overcoming the aforementioned bottlenecks. Inspired by this mechanism, researchers have begun studying brain-inspired bionic circuits.

[0004] The core of neuromorphic bionics lies in simulating the plasticity of biological synapses. Traditional circuits mostly use CMOS transistors, capacitors, and resistors to simulate biological synapses, but this still has many limitations. For example, traditional synapses have low integration density, and synaptic weights are easily lost when power is off. The emergence of memristors has made it possible to construct novel synapses. Memristors have plasticity and non-volatility; their resistance changes with the voltage applied across them, and their resistance remains unchanged after power is off.

[0005] In addition to its resistance flexibility and non-volatility, memristors also feature nanoscale size, low power consumption, compatibility with CMOS processes, and suitability for large-scale integration. Therefore, using memristors to build memristor-inspired circuits is one of the feasible solutions for realizing brain-like bionics.

[0006] With in-depth research, biomimetic circuits based on memristors have made significant progress in recent years, successfully realizing various learning mechanisms such as non-associative learning and operant reflex conditions. Meanwhile, some studies have begun to incorporate emotional factors, focusing on exploring the influence of emotions on behavior. However, most existing work treats emotional signals as static or modulated signals, neglecting the dynamic characteristics of emotions themselves becoming habituated with repetition of stimuli. More importantly, it has not clearly established the interaction between the emotional system and the habit system. It is this interaction that constitutes the synergistic mechanism of "emotion driving behavior, behavior forming habits, and habits modulating emotions" in biological intelligent decision-making. Based on this, this invention proposes a memristor decision-making circuit that integrates emotional habituation and behavioral reinforcement, simulating the habituation of emotions and the reinforcement of behavior to achieve their interaction. This invention combines the novel electronic device memristor with biomimetic principles, providing a new hardware implementation scheme for researching brain-like intelligent decision-making systems, and demonstrating potential application value in autonomous robots, intelligent agents, and other application scenarios. Summary of the Invention

[0007] Addressing the limitations of current memristor-based bionic circuits in simulating the interaction between emotion and habit systems, this invention proposes a memristor decision circuit that integrates emotional habituation and behavioral reinforcement. It utilizes the plasticity of a novel two-terminal memristor to simulate the dynamic changes in different emotional intensities and the formation of behavioral habits. Changes in emotion influence behavior, repeated execution of behavior leads to habituation, and habituation modulates emotions. This invention simulates this process at the hardware level.

When the resistance of M2 reaches 4.5kΩ, it indicates that decision-making habits have been formed, such as... Figure 2 As shown.

[0012] In the emotion generation module, the dynamic changes in emotions are simulated by the resistance changes of memristors M1 and M2. Higher memristor resistance indicates lower emotion intensity, and vice versa. In V in In one cycle, during the first half of the cycle, the output signal of COM1 is applied to the negative terminal of memristor M1 and the positive terminal of M2. The resistance of M1 increases, while the resistance of M2 remains unchanged due to the stability of long-term emotions. The resulting emotional signals are weighted and summed before being input to the decision output module to generate a decision result. In the second half of the cycle, the circuit generates a feedback signal based on whether the decision result is correct or incorrect. If the decision is correct, a feedback signal V for the short-term emotional path is generated. at1 and feedback signals V to long-term emotional pathways at2 V at1 This will decrease the resistance of M1, simulating the fading of short-term emotional memory when the positive signal disappears. However, the reduced resistance will be greater than the resistance at the time of the previous decision, simulating the residue of emotional memory. V at2 This will increase the resistance of M2, simulating the long-term emotional habituation process. The long-term emotional signal generated by the next positive input will weaken. After making correct decisions many times, a decision-making habit will be formed. The formation of the decision-making habit is represented by the resistance of the memristor M2 reaching a preset value. If the decision is still correct after the habit is formed, the circuit will then adjust the output signal of COM1 and V. at1 and V at2 The value is adjusted so that it no longer meets the threshold conditions of M1 and M2. The resistance values ​​of M1 and M2 will then remain unchanged, simulating a state where emotional fluctuations cease as habits are formed. If the decision is incorrect, a feedback signal V for the short-term emotional path is generated. af1 and feedback signals V to long-term emotional pathways af2 V af1 This will reduce the resistance of M1, but the reduction will be greater than when the decision is correct, and emotional memories will fade more. af2 This will decrease the resistance of M2, simulating the long-term emotional dehabitation process, and the long-term emotional signal generated by the next positive input will be stronger. If two incorrect decisions are accumulated, the circuit will not make a decision when a positive signal is input again, and there will be no feedback signal for correct or incorrect decision. At this time, the forgetting signal V... forget11 and V forget12 This significantly reduces the resistance values ​​of M1 and M2, allowing the circuit to relearn upon the next positive signal input.

When the resistance of M6 reaches 4kΩ, it indicates that the decision circuit has formed a habit, such as... Figure 3 As shown.

[0019] In the emotion generation module, the dynamic changes in emotion are simulated by the resistance changes of memristors M5 and M6. Higher memristor resistance indicates lower emotion intensity, and vice versa. In V in In one cycle, during the first half of the cycle, the output signal of COM2 is applied to the positive terminal of memristor M5 and the negative terminal of M6. The resistance of M5 increases, while the resistance of M6 remains unchanged due to the stability of long-term emotions. The resulting emotional signals are weighted and summed before being input to the decision output module to generate a decision result. In the second half of the cycle, the circuit generates a feedback signal based on whether the decision result is correct or incorrect. If the decision is correct, a feedback signal V for the short-term emotional path is generated.bt1 and feedback signals V to long-term emotional pathways bt2 V bt1 This will decrease the resistance of M5, simulating the fading of short-term emotional memory when the negative signal disappears. However, the reduced resistance will be greater than the resistance at the time of the previous decision, indicating that residual emotional memory remains in the simulation. bt2 This will increase the resistance of M6, simulating the long-term emotional habituation process. The long-term emotional signal generated when a negative signal is input again will weaken. After multiple correct decisions, a decision-making habit will be formed. The formation of this habit is represented by the resistance of memristor M6 reaching a preset value. If the decision remains correct after the habit is formed, the circuit will then adjust COM2 and V... bt1 and V bt2 The value is adjusted so that it no longer meets the threshold conditions of M5 and M6. The resistance values ​​of M5 and M6 will then remain unchanged, simulating a state where emotional fluctuations cease as habits are formed. If the decision is incorrect, a feedback signal V for the short-term emotional path is generated. bf1 and feedback signals V to long-term emotional pathways bf2 V bf1 This will reduce the resistance of M5, but the reduction in resistance due to incorrect decision-making is much greater than the reduction due to correct decision-making, and emotional memory will fade more significantly. bf2 This will reduce the resistance of M6, simulating the long-term emotional dehabitation process, so the long-term emotional signal generated by the next negative input will be stronger. If two incorrect decisions are accumulated, the circuit will not make a decision when a negative signal is input again, and there will be no feedback signal for correct or incorrect decision. At this time, the forgetting signal V... forget21 and V forget22 This significantly reduces the resistance values ​​of M5 and M6, allowing the circuit to relearn when a negative signal is input next time.

[0023] The memristor decision circuit proposed in this invention includes a positive signal input path and a negative signal input path, with input signal V inAfter passing through COM1 and COM2, only one of them will have an output signal, while the other will output 0V. With repeated application of stimuli, the short-term and long-term emotional signals of the emotion generation module will gradually weaken, and the time required to make a decision will gradually shorten. Simultaneously, the repeated execution of the decision will form a habit. When the resistance values ​​of memristors M2 and M6 in the long-term emotional path reach a certain threshold, it indicates the formation of a habit. After habituation, the short-term and long-term emotions will tend to stabilize, and the resistance values ​​of M2 and M6 will no longer change. The decision-making circuit can also make decisions incorrectly. A decision error occurs when the input signal V... in Errors, such as V in This should have been a negative signal, but due to an incorrect input V... in To illustrate this, let's take a positive signal input path decision error as an example. V in What should have been a negative signal is instead a positive signal. In this case, the positive signal input path will produce a decision output, but after verification, the decision is found to be incorrect. The feedback signal causes the resistance of memristors M1 and M2 to decrease. The next positive signal input will generate a stronger emotional response, leading to more cautious decision-making because the previous decision error was caused by the positive signal. After two accumulated decision errors, the decision threshold becomes negative, and the circuit will not make a decision when a positive signal is input again. The positive signal input path will remain locked. To prevent this lock-up, a recovery signal V is introduced. restore1 At the same time, a forgetting signal V is introduced. forget11 and V forget12 , recovery signal V restore1 This lockout is released by increasing the resistance of memristor M3 in the decision output module and decreasing the resistance of memristor M4 in the threshold adjustment module, while the forgetting signal V... forget11 and V forget12 This significantly reduces the resistance values ​​of memristors M1 and M2 respectively, when V... in When the signal is positive, the positive signal input path restarts the decision-making process.

A 5V pulse signal is applied for the first half of the period (0.5 seconds), and 0V is applied for the second half of the period (0.5 seconds). During the first half of the period, V... in This causes the resistance of M1 to increase; due to the stability of long-term emotions, the resistance of M2 remains unchanged in the first half of the cycle; in the second half of the cycle (0.5s), the circuit generates a feedback signal V based on the decision result. at1 and V at2 V at1 This will decrease the resistance of M1, but the reduced resistance will be larger than the initial resistance. Overall, the change in the resistance of M1 shows an upward trend. at2 This increases the resistance of memristor M2, and the increase in M1 and M2 weakens the emotional intensity generated when a positive signal is input again. As V... in The application of this effect causes the decision-making circuit to form a decision-making habit. When the resistance of memristor M2 reaches 4.5kΩ, it signifies the formation of this habit. Once the habit is formed, the resistance of the memristor no longer changes, and both short-term and long-term emotional signals tend to a stable value. Furthermore, the speed of decision-making also changes. Initially, making a decision takes approximately 0.4 seconds; after a successful decision, the next decision takes 0.22 seconds.

Once this habit is formed, the memristor's resistance no longer changes, and both short-term and long-term emotional signals tend towards a stable value.

With the 4th decision error, the resistance values ​​of memristors M1 and M2 decrease significantly, the decision threshold decreases, and the 5th decision takes longer than the 4th decision due to the 4th decision error, indicating a more cautious decision-making process. Simultaneously, the short-term and long-term emotions generated by the 5th decision are also enhanced due to the 4th decision error. The 5th decision is also set as a failure; at this point, the cumulative decision error is 2, and the threshold voltage V... threshold1 It will drop to a negative value. A positive signal is applied for the 6th time, due to the threshold voltage V. threshold1 If the value is negative, the circuit will no longer make a decision. Meanwhile, between 5.5s and 6s, the repair signal V... restore1 Reduce the resistance of memristor M4 to restore the threshold voltage V. threshold1 Forgotten signal V forget11 and V forget12 This significantly reduces the resistance values ​​of memristors M1 and M2, so that when the next positive signal arrives, the circuit restarts its decision-making and learning process.

The circuit makes correct decisions in the first 3 seconds, and makes incorrect decisions in the 4th and 5th seconds. In the first 3 correct decisions, the short-term and long-term emotional signals gradually weaken, and the decision-making time gradually shortens. In the 4th decision error, the resistance values ​​of memristors M5 and M6 decrease significantly, the decision threshold decreases, and in the 5th decision, due to the 4th decision error, the decision-making time is longer than the 4th, the decision becomes more cautious, and the short-term and long-term emotions generated by the 5th decision are also enhanced. The 5th decision is also set as a failure. At this point, the cumulative decision error is 2, and the threshold voltage V... threshold2 It will drop to a negative value. The 6th negative signal is applied due to the threshold voltage V. threshold2 If the value is negative, the circuit will no longer make a decision. Meanwhile, between 5.5s and 6s, the repair signal V... restore2 Reduce the resistance of memristor M8 to restore the threshold voltage V. threshold2 Forgotten signal V forget21 and V forget22 This significantly reduces the resistance values ​​of memristors M5 and M6, so that when the next negative signal arrives, the circuit restarts its decision-making and learning process.
